Rolls-Royce Corp. has been awarded a contract, worth around $1.2 billion, to provide sustainment support for the AE 1107C-Liberty (T406) turboshaft engine that powers the Bell-Boeing V-22 Osprey tiltrotor aircraft.
The firm-fixed-price, indefinite-delivery/indefinite-quantity contract was awarded by the U.S. Department of Navy’s Naval Air Systems Command (NAVAIR). According to a Pentagon contract announcement, this contract “provides sustainment support of the V-22 AE1107C engine at various V-22 aircraft production, test, and operating sites”.
Under the Rolls-Royce MissionCare contract, the company will be responsible for all aspects of propulsion system support, on a Power by the Hour basis.
Sustainment support includes program management, integrated logistics support, sustaining engineering, maintenance, repair, reliability improvements, configuration management, and site support. Work will be performed in Indianapolis, Indiana, and various locations within and outside the continental U.S., and is expected to be completed in February 2025.
Paul Craig, Rolls-Royce, President – Services, said, “Rolls-Royce has supported the warfighter and these remarkable, revolutionary aircraft since they entered service in 2007. Our MissionCare services model ensures the warfighters are focused on their missions, not their engine availability. Rolls-Royce is proud to serve the Marine Corps, Navy and Air Force and contribute to the success of V-22 missions around the world.”
The Rolls-Royce AE 1107C-Liberty (U.S. military designation: T406) is a turboshaft engine, delivering 6,000 shp (4,470 kW), developed by Allison Engine Company/Rolls-Royce plc.
The T406/AE1107C Liberty shares a common core with the AE 3007 (U.S. military designation: F137) turbofan and AE 2100 turboprop series of aircraft engines
The T406 engine powers the Bell-Boeing V-22 Osprey tiltrotor aircraft operated by the U.S. Marine Corps and the Air Force. The aircraft is also ordered by the U.S. Navy for Carrier onboard delivery (COD) missions, designated as CMV-22B.
Rolls-Royce has delivered nearly 1,000 AE 1107C engines for V-22 aircraft in operation around the world. The total fleet of more than 375 MV-22s and CV-22s in service recently topped 500,000 flight hours – or 1 million engine hours on the twin-engine aircraft.
